Subject [generation] Progress on the code generation ...
Date Wed, 10 Apr 2019 18:27:11 GMT
Hi all,

just wanted to keep you all in the loop (I’ll try to use the [generation] as marker for
this topic).

I just committed some changes to the “plc4x-maven-plugin”.

And I also noticed I should explain why this module is not integrated into the build.
Maven is quite good at resolving dependencies at runtime and ordering the reactor order accordingly
to build what’s needed before it’s needed.
Unfortunately this doesn’t work for plugins. So if we use the “plc4x-maven-plugin” in
the rest of the build, building will fail guaranteed and especially during releases get really
So some time in the future we will have to release this plugin independently from the rest
of PLC4X (Hopefully we’ll not have to re-release it too often though).
And being able to release it separately is also the reason why it directly references the
Apache parent and not any PLC4X parent.

So now to the plugin … if you want to see a first draft, simply run at least a “mvn package”
build inside the “sandbox/plc4x-maven-plugin” directory.
Part of the build is a maven plugin unit test, that executes the build defined in “plc4x-maven-plugin/src/test/projects”
in the directory “plc4x-maven-plugin/target/test-projects”.
Please have a look at the later directory to see what it generates in “plc4x-maven-plugin/target/test-projects/GenerateMojoTest_testSomething_simple-embedded-schema/target/generated-sources/plc4x”

Yeah … a lot of directories … but this way you can at least see what I’m up to :)

But still a lot of cleaning up to do … especially the handling of datatypes … currently
the xml simpleTypes defined in the schema are used, I have to translate them into language-dependent
types …
